Title: Improvements in or relating to weaving
IPC: D03D15/00
Filed: 1960-05-13
Abstract: 938,586. Woven fabrics. H. M. CLOVER, and WOVEN PLASTIC PRODUCTS Ltd. May 2, 1961 [May 13, 1960], No. 16925/60. Classes 42 (1) and 74 (2). [Also in Groups IX and XIV] Floor or table matting is woven from a warp of polyvinyl chloride tubes which flatten where they pass over and under the weft. The warp tubes may have a core of soft string or they may be in the form of flat strips having two or more bores. The weft may be sisal yarn or may be of polyvinyl chloride, either solid or as a sheathing on a core of string or wire. Finishing edges.-The cut edges of a mat may be covered by two pieces 4 of polyvinyl chloride, Fig. 4, or by one piece folded round the edge, or by a U-section extrusion, and sealed by highfrequency heating between electrodes. In the case of a table mat, the material of the mat itself may be fused by an electrode 7, Fig. 6, which also indents the periphery to enable surplus material to be torn away, leaving a mat of the desired shape.

Title: Improvements relating to pneumatically operable control mechanism
IPC: H01H33/32
Filed: 1939-06-09
Abstract: 529,866. Pneumatic single-stroke devices. BRITISH THOMSON-HOUSTON CO., Ltd. (Shibaura Engineering Works, Ltd.). June 9, 1939, No. 16970. [Class 8 (ii)] [Also in Group XXXVII] Pneumatic means for moving a member such as the rotatable control shaft of an electric controller into selected positions comprises a free piston 5 and successively smaller connected pistons 3, 2 which operate the member, e.g., through a link 8, the small piston 2 being continuously subject to pressure from an air pipe 9 which also can supply air under pressure through valves 10, 11 to the outer face of the large piston and/or the space between the large and intermediate pistons, the valves in their other positions connecting these spaces to atmosphere. The large piston acts as a stop in one or other position, limiting the movement of the connected pistons in one direction.

Title: Fluid pressure control valve
IPC: G05D16/06
Filed: 1963-04-30
Abstract: 984,326. Valves. MINISTER OF NATIONAL DEFENCE OF H.M. CANADIAN GOVERNMENT. April 30, 1963 [April 30, 1962], No. 16974/63. Heading F2V. A pressure regulator 1 has an inlet 4 and an outlet 5 leading to and from a chamber 2, one wall of which is formed by a diaphragm 20. The inlet 4 is angled and connected to a rigid tube 9 by a chemically-inert flexible-tube 8; the outer bevelled end of the tube 9 is attached to the diaphragm 20 by a rod 13. When the pressure in the chamber attains the desired level the diaphragm, which may be weightloaded, lifts the tube 9 so causing the flexibletube 8 to fold or pinch and prevent or throttle fluid flow therethrough. The flexible-tube may be made of rubber which is pre-stressed in a folded form at 80 C. for twenty-four hours before use; the rigid tube 9 may be dispensed with. The diaphragm may be of rubber which is coated with polyvinylidene chloride in acetone, the latter then being evaporated; a piston-and-cylinder may replace the diaphragm. In another form the diaphragm is loaded by fluid pressure supplied to a chamber above the diaphragm through a needle valve. In a further form, the valve is used to maintain a given level of vacuum or pressure; in the latter case, the inlet and outlet are reversed, the flexible-tube being folded when the diaphragm is lowered or lifted. The upper diaphragm surface may be vacuum or pressure loaded.

IPC: B64C23/00
Filed: 1960-05-16
Abstract: 938,793. Aircraft. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. May 11, 1961 [May 16, 1960], No. 17165/60. Addition to 921,013. Class 4. An aircraft is powered by a plurality of gas turbine jet propulsion engines 6 of the by-pass type connected to discharge their turbine exhaust gas streams clear of the wings through rearwardly directed jet propulsion nozzles 21 and to supply at least part of their by-pass streams through non-return valves 26 to a common duct 25, the duct being connected to nozzles 29 to discharge air as long thin streams extending along the span of the wings, the aircraft further comprising means 32 to reduce the flow area available for the discharge of the by-pass streams relative to the flow area available for the discharge of the remainder of the efflux of the engines, said means being operable in response to an indication of failure of any one of the engines. The invention is an improvement on that described and claimed in the parent Specification wherein each non-return valve 26 in the duct 24 leading from each engine to the common duct 25 feeding the wing jet nozzles comprises a pair of flaps 41 held open against spring-action by the flow of air. One of the flaps of each pair carries a contact arm 42 for a switch 43, the switches being in series with a motor 44, which, when any one of valves 26 closes is energised to close valve 33 in auxiliary nozzle 32, thereby reducing the flow area available for the discharge of the by-pass streams. Alternatively nozzle 32 may be dispensed with and motor 44 used to control valves in either the by-pass ducts or the wing- jet nozzles. Specifications 758,269 and 883,865 also are referred to.

Title: Improvements in Electric Fusible Cut-outs.
Inventor: TRENT HAROLD ERNEST
IPC: H01H85/055
Filed: 1918-10-28
Abstract: 134,290. Trent, H. E. Oct. 28, 1918. Fusible cut-outs.-Fuse wires or strips of lead or zinc are covered at intervals along their length with a compound of good heat distributing and dissipating qualities but of poor electrical conduotivity, so as to reduce the temperature of the fuse at the covered parts and ensure fusion first at the uncovered parts. A covering having these properties may contain a minimum of vaporizable material, and the covering itself may serve to cushion the effects of the explosion. In the arrangement shown in Fig. 1 applied to a strip cartridge fuse, the strip, which is of uniform cross-section, is covered at 7, 8, 9 with a mouldable compound made of asbestos fibre, manganese dioxide, feldspar, and plaster of paris, mixed together with silicate of soda to form a paste. The strip may be reduced in width at the exposed parts. A compound fuse may be made up of a number of wires connected in parallel to terminal blocks, all the wires being covered together, at intervals, with the compound. A cartridge fuse made up of a single wire covered as described may be under spring tension. A single wire may be enclosed by a tube of the compound, the tube having perforations at intervals so as to leave the wire substantially uncovered at these intervals. The tube may be covered by an outer tube of asbestos or shellaced paper.

A cotton comber has the feed rollers and nipper assembly mounted for relative movement so that when the nipper assembly is in its foremost position, Fig. 7A, it is nearer to the feed rollers than when it is in its rearmost position, Fig. 7B. The mechanism is adjustable so that, alternatively, the nipper assembly and feed rollers may be nearer in the rearmost position, or the distance may be equal in both positions. It is stated that with the distances as first set out waste can be reduced to 3%, whereas with the second arrangement waste may be in excess of 8%. The swinging movement of the nipper assembly is derived from a nipper shaft 55, Fig. 2, and the rear of the nipper body 51 is supported by an oscillating arm 54 with the front pivoted to a swing arm 40 by a pin 30. Also pivoted on the pin 30 is a bracket 20 normally maintained in a fixed relation to a feed roller bracket 2. Brackets 2, 20 are caused to swing on the pin 30 by a feed roller shaft 35. The cushion plate 50 of the nipper assembly moves forward to the same position on each movement irrespective of the proportion of waste required. Alteration in the proportion of waste is obtained by adjusting the distance between the foremost position of the feed rollers 1, 10 and the first detaching rollers 75. This adjustment is effected by a slotted sector arm linkage located between shafts 35, 55 (Fig. 4 not shown). To reduce or eliminate risk of damage by collision of the feed roller 1 with cushion plate 50, a spring 18 is connected to the bracket 20 and to a lever 14 mounted on the feed roller bracket 2 in such manner as to allow relative movement of parts.
